蘸花结合叶面喷施微量元素对番茄果实的影响

Effects of Dipping Flowers and Spraying Micro Elements on Leaves on Development of Tomato Fruits

选用改良丰产剂2号、丰产剂2号于始花期对番茄进行蘸花及结合定期叶面喷施中、微量元素,比较分析各小区番茄的坐果率、膨大速度、前期产量、总产量、果实直径,以筛选适合设施番茄生产的植物生长调节剂配方。试验结果表明,用改良丰产剂2号蘸花并结合定期叶面喷施中、微量元素的处理在提高番茄坐果率、产量方面均有很好的效果,优于其他3种植物生长调节剂配方和对照;用改良丰产剂2号和微量元素混合液蘸花处理在提高平均单果质量和改善果实形状方面优于其他3个配方处理及对照;用丰产剂2号蘸花处理能更好地提高番茄的前期产量。综合各项指标来看,用改良丰产剂2号蘸花并结合定期叶面喷施中、微量元素的配方对设施番茄果实发育效果最好,用改良丰产剂2号和微量元素混合液蘸花的配方次之。

In order to screen out suitable plant growth regulator formula for facilities tomato, we investigated and compared fruit-setting rate, expanding speed, prophase yield, total yield and fruit diameter of different treatments, by dipping different concentrations of Fengchanji No.2 and improved Fengchanji No.2 on tomato flowers at early flowering season and spraying secondary and micro elements on tomato leaves regularly. The results showed that treatment 6, dipping flowers with improved Fengchanji No.2 and spraying secondary and micro elements regularly, had better effects on improving fruit-setting rate and yield of tomato, and the treatment d, dipping flowers with improved Fengchanji No.2 and secondary and micro elements, had better effects on increasing average fruit weight and improving fruit quality, while the treatment 5, dipping flowers with Fengchanji No.2 and spraying secondary and micro elements on tomato leaves regularly, could increase the prophase yield preferably. Comprehensively, treatment 6 possessed the best effects on promoting the development of facilities tomato fruits, and the treatment 4 took the second place.
